This invention relates to windpower and is titled "A Windtrap For Power Development". It is designed to take power from the wind by turning a vertical mast. The intention is to hold the total wind force that comes within the dimensional area of each unit when the said unit comes to the power side, then have the trap automatically close and feather the wind on the return side of the revolving mast. Feathering on the return side is assisted by: a) a cable from a wing arm to the top side frame of the trap to hold same horizontal when on the return side, and b) two torsion springs on each unit attached, one to each end of the lower side frame of trap. The springs must carry 60% to 70 % of weight of the lower trap side section. Torsion helps wind lift the lower side towards the horizontal on the return side of mast and leaves 30% to 40% of the weight so gravity cam open it again on the power side. A partial balance is set by the torsion springs, between gravity, the trap design and wind force, to give continuous opening and closing, with the trap holding full wind force on power side and giving minimum resistance on return side.
